can we get a confirmation if Eyefinity works with 3 x DVI LCDs when using two of the 5870 cards ?

thanks


I think Dave already confirmed that Eyefinity across cards is currently not supported.

[quote][quote]So in the projector setup I'm building I can use 2 passive single-link dp to dvi adapter and 3 active dp to dvi adapter to achieve my goal of 5 DVI based displays?

That should work.

IIRC - we have heard about one vendor interested in a single link active adapter which should be cheaper than then active ones. I need to check on the status of those as to whether or not they are a go.

It definitely would be of interest to most people in the forums. I know most of us are 22" or 24" display setups which only need single-link. If that vender can pull off cheap single-link active adapters I'll be the first in line for 3 or 4 (plus one of those 6-port cards). I have money on hand this second for the purchase. :wink:

Yep, that would do it for me.

I want the Eyefinity6 card.
I am prepared to get 3 DP monitors for it so no problem with TH surround BUT I also want to make use of the remaining 3 outputs.

IF those three outputs (all six for that matter) can support single link resolutions (i.e. up to 1920 x 1200) purely via a passive DP to DVI connection then I will be very happy.

Dave, could you confirm whether the DP+ outputs of the Eyefinity6 card will be able to drive DVI/HDMI panels up to single link DVI resolutions by using a passive DP to DVI connection alone. I would assume they should since that is the '+' part of the spec as far as I can see. Thanks.

I learned a lot reading this thread.

Just one clarification. I see Eyefinity doesn't work with windows XP.

Will three monitor support work with windows XP? Just for regular desktop content, not eyefinity?

I was told that this adapter features an active conversion inside. I ordered it hoping it works. I am waiting on the 5870x2 though for my triple screen setup.

Here is the manufacturer site with more info stating it is an active adapter.

No, they will definitely NOT work. You need an adapter that is powered by an usb connector.

That definitely makes me sad :( as the only one available is the Dell coming in at $100 plus shipping. It was confirmed that the apple one is useless.

[quote] - Display Port being a MUST to triple screen game ( how many Gamers have a monitor with DP, not too many, and only the newer Dell's and HP have that connection, which are rather pricey displays, so all the good priced monitors or us with old monitors are left out ? )

As I've said, DisplayPort is the enabler to this technology, its not feasible to offer it as a "no extra cost" value add feature without it.

I don't think anyone here is asking for ATi to do a "no extra cost" value add feature. I think what most of us are saying is that there should be some variation of the card that does away with DP and uses all DP+ that we'll happily pay the premium for over having to deal with active adapter costs. Would DP+ port not cost us less than a bunch of active adapters? With that in mind, is the architecture capable of 6 DP+ ports on the 6 mini-dp card? For the 6-port card to be the most flexible card targeted at multi-display users, ATI is setting the requirements out of reach of most everyone by not going DP+. This either forces people to purchase multiple active adapters or multiple DP displays. DP simply has almost zero market saturation at this point making this requirement a bit unfeasible for most that would be interested in this card. There is a pre-established market for EyeFinity and it's not currently properly targeting it. EyeFinity should set the bar low enough to allow it to gain acceptance and the DP requirement is an impediment to that, especially if DP+ could be used for a marginal increase in cost.

How much price difference is there in the manufacture of a DP port vs a DP+ port? One would not think it was equal to the price of a $100 active adapter or for that matter 1/10th the price. I'm not getting the economics here as far as a card like the 6-port can't have all DP+ electrical port outs?

While you're coming at this from the larger picture and as a manufacturer, those of us here come at it from the perspective as the established surround-screen gaming community that simply doesn't have any market saturation at all of DP based products. There seems to be a lack of marketing research that was done when looking into the EyeFinity target market. You openly admit only just a few days ago even finding WSGF, which has had a focus on this type of technology for years now. I'd say almost 100% of the WSGF is DVI/HDMI based multi-display. The lack of DP+ and the adapter issue is making what would otherwise be a wonderful new tech and putting roadblocks in place for acceptance. By only using DP, ATI is passing the buck as far as user expense to all of us who will have to now go track down active adapters.

In order to gain wider acceptance I think most of us would be willing to pay a price premium for DP+ based cards. A price premium built into the card for DP+ is significantly less than hiding the cost and passing it onto the consumer via active adapter price premium.

I know people said it will not work and I have my doubts.

but let it come and test it for real...

hey if it works even in single link mode (that's fine for many people as it goes up to 1920x1200) .. then u stumbled upon a cheap adapter for us to get and will be hail as a hero... :)

So im a bit confused by this thread, i was about to get a 5870 and now im not sure if i should.

With my setup, i have 3 * 24 Dell LCDs, all only have DVIs.

Do i need to get a $100 Active DP converter, or can i use an HDMI to DVI converter to drive the third monitor, while conecting the other 2 monitors to the DVI ports?

Thanks
